There are lots of new features in SwiftKey 5 too, but the important ones you need to know are:

SwiftKey Store: The keyboard app now has in-app purchases for add-ons starting with free and premium themes.

Emoji: SwiftKey not supports over 800 emojis on devices running Android 4.1 or above, and these also come with optional emoji prediction! For example, type “burg” and the burger emoji appears.

Number row: Finally, finally there is the option to add a new row at the top of your keyboard for numbers, which you can enable or disable in Settings > Layouts.

The update has also improved the prediction engine of the app, with a focus on improving multilingual prediction, so you can type in up to three languages at once! Speaking of which, SwiftKey now supports 66 languages at a contextual level and has recently added Belarusian, Mongolian, Tatar, Uzbek and Welsh.

In case you already paid for SwiftKey Keyboard and feel cheated, the company is giving you a pack of 10 premium themes for free, worth $4.99. It’s small consolation, but the free themes don’t look as good, so this is welcome. Here’s how to claim your premier pack.

I probably will step on somebodies' toes, but I think feeling cheated because one once paid for an app that is now free is idiotic and childish. I did pay for SwiftKey because it's a great product. But that didn't grant me anything in terms of their future plans and I wasn't forced to buy it, so how could I feel cheated? Makes no sense at all.

I'm one of those users that feels a bit cheated after having paid for the app, but it's really not that big of a deal—it happens every once in a while.

I can't speak highly enough of SwiftKey, though; it's one of the best Android apps out there, I think. My mobile typing has improved tenfold since I downloaded it, and the more you use it, the better the prediction engine gets. Get it!

This is exciting! I've long urged people to download SwiftKey and told them it's worth paying for. Now they don't have to.

I just hope they keep the in-app purchases to themes only, and not core features of the keyboard. That being said, some of the new themes are great-looking. Can't wait to try some of the ones I got free.
